Sarah Ferguson will document her mental health battles in new young adult books

The 62-year-old author - who is the ex-wife of Prince Andrew - has announced she is set to pen several tomes, including three new young adult novels based on her own life, via publishers Serenity Press.

The Duchess of York - who has Princess Eugenie, 32, and Princess Beatrice, 33, with Queen Elizabeth's son - will open up about her own struggles with mental health and an eating disorder, as well as the loss of her mother Susan Barrantes, who died just one year after Princess Diana in a car crash.

Sarah said in a statement; "Young adults are perhaps the fastest-growing category of new fiction today. There's just something about adolescence — with all its incredible triumphs and heartbreaking failures— that makes it the perfect backdrop for powerful storytelling."

She added: "I wanted to share my story of growing up with anxiety and an eating disorder, along with witnessing firsthand the effects of generational trauma. For me, it is always present and it all started at the loss of my mother."

The first book, 'Demon's Land', is part of The Southport Series co-written by Michelle Worthington, and will arrive at the end of June.

Sarah released her debut novel, coming-of-age tale 'Her Heart for a Compass', last summer, and she's set to release part two in January.

The Sarah's Trust founder has recently spent time in Poland visiting Ukrainian refugees, and her "constant contact" with young people around the globe has proved inspirational.

She added: "With my charity work, I'm in constant contact with young people and I have so much empathy for everything they have been through in the past two years. They are a capable and compassionate generation and their help as consultants on this book to make sure we captured the essence of what it's like to be a teenager today was instrumental in the writing of the book."

Co-writer Michelle commented: "I was honoured to be asked to form part of this project and always enjoyed my brainstorming and writing sessions with The Duchess. I very much appreciate her warmth, professionalism and value highly her advice based on extensive research into her YA audience.

"She went out of her way to articulate and clarify exactly what messages she wanted to share in the series based on her personal experiences and took the time to listen to mine. Her personalised approach challenged me to improve the manuscript and become the best support I could be to her vision. This series is a testament to her courage."
